Abstract: PURPOSE:To simplify construction of a flow path and to promote stabilized action or the like, by providing a jet stream injecting supply nozzle, inducing chamber having an opening communicating with the atmosphere and a side wall so that deflecting oscillation of a jet stream is performed with out providing a feedback flow path. CONSTITUTION:Inflow fluid to a supply flow path 6 is injected from a supply nozzle 7, and this jet stream Fil becomes a high speed flow in an inducing chamber 8, causing it to generate a pressure not more than the atmospheric pressure. As a result, air, which passes through a gas introducing port 9, is induced into the inducing chamber 8, and gas vortexes VL1, VR1 are formed in both sides of the jet stream Fil. Here the jet stream Fil, if its upper side gas vortex VL1 low decreases the pressure, is previously deflected to an upper side being jetted from a jet port as a stream FO1. Next, on part of a gas vortex VL2, formed by a jet stream Fi2, is allowed to flow out from the inducing chamber 8 as a bubble B, and its inflow to a part of low pressure vortex AL2 destructs a low pressure condition between the jet stream Fi2 and a side wall 11. As a result, the jet stream Fi2, which straight advances as a jet stream FO2, is jetted from the jet port.

Title: Switch matrix
Inventor: SHIGEMATSU TOMONORI
IPC: H03K17/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To suppress the deviation of a gain at the time of conducting between input and output terminals by providing an amplifier for compensating a loss deviation between the input and output terminals different in path length of a switch matrix to an input line, an output line or both of those lines. SOLUTION: A switch matrix has an amplifier 25 provided on both of input and output lines. This amplifier 52 is equipped with a matching inductor 53 and a matching resistance 54. A signal wave inputted from an input/output terminal 1 lowers a level of the signal wave by a resistance element of a unit switch 11 or a line loss as the wave passes several input/output matching inductors 5 and an intersection part 12 of the input/output lines. The level of the signal waves becomes lower with regard to an output line 4 as well. A gain of the amplifier 52 provided to input lines 2 and 4 is set so that the level of the signal wave to be inputted or the level of the signal wave to be outputted becomes equal in any unit switch 11. Thus, a deviation occuring to the level of the signal wave to be outputted to each output terminal 3 is prevented.
